Filed Sept. 27, 1928 Inventor Fred F005 Attorney Patented Oct. 22, 1929 FRED F008, OF SAN FERNANDO, CALIFORNIA NAIL Application filed September 27, 1928. Serial No. 308,817.

7 My invention relates to improvements in nails and aims to provide means throughout its shank to prevent the creeping upwardly or accidental displacement of the same after the nail has been driveninto the wood.

Another object of my invention is the provision of a nail which can be manufactured at approximately the same cost as the ordinary nail in common use and serves as a very efiicientimprovement thereon.

v With these and other vobjects in view the present invention consists in its novel features as will be hereinafter more fully described and shown in the accompanying l5 drawings, it being understood that changes in the form, proportion, size and minor details may be made within the spirit and scope of the appended claim without sacrifi cing the advantages of my invention.

In the drawing:

The figure is an enlarged perspective of the improved nail.

WVith particular reference to the drawing numeral 1 indicates generally a nail having a shank 2, said shank having a head 3 formed at one end and a point 4 at its opposite end.

The shank is of an increased thickness at a point intermediate the head and point and preferably a little below the center of the shank. At opposed points longitudinally extending notches 5 are formed in the thickened portion of theshank to provide spaced shoulders 66 at opposite sides of the nail. At the end of these shoulders the surface of the thickened portion gradually merges into the surface of the nail shank to facilitate driving and releasing of the nail into and from the wood.

' At opposite ends of said enlargement the to shank is formed with a pluralityof substantiallyV-shaped notches 7 in spaced relation and extending downwardly with respect to said shank 2.

It will thus be seen that a nail constructed pand during the driving operation and contract after completion of the same so that the fibers will settle betweenthe shoulders 6-6 and in the strips between the barbs on said shank.

It is to be understood that the form of my invention herein shown and described is to be taken as the preferred example of the same and the various changes in the shape,

size and arrangement of the parts may be resorted to without departing from the spirit of the invention or the joined claim.
